7G SOLIDS, LIQUIDS AND GASES

7E acids and alkalis
7F SIMPLE CHEMICAL REACTIONS
7h solutions
In this topic you will learn that everything is made from particles and how these particles are arranged in solids, liquids and gases. You will understand what causes air and water pressure as well as diffusion.

I can
  • draw the particles in a solid, liquid and gas
  • explain what happens when a substance changes state
  • explain air pressure
  • explain water pressure

I understand
  • that all substances are made of particles
  • how particles are arranged and move in solids, liquids and gases
  • that some substances are difficult to classify as solids, liquids or gases
  • what happens in boiling /evaporation, melting, freezing, and condensation
  • what causes air pressure
  • what happens to water pressure as you go deeper

useful 7g websites

BBC Bitesize. Click here for the bitesize information about solids, liquids and gases.

BBC Bitesize. This link has information about pressure, diffusion etc.

Look at this animation that shows the particles in water, ice and water vapour.

Learn about changes of state by looking at the particles in this animation from Pearson.
